Application filed July 1,

Our invention relates to railway rolling stock and consists in an improved construction of underframing and superstructure for railway vehicles intended primarily to carry 6. liquid and our invention is vparticularly adapted for use in locomotive tender construction. One object of our-invention is to provide an improved underframe casting which in itself may form the bottom of a tank structure and upon which the sides and ends of the tank may be mounted thereby lightening the weight of the whole vehicle. Another object of our invention is to utilize the heavy tank-forming plates of the superstructure as load transmitting girders supplementing the underframe sills, thereby making it possible to lighten the latter.

Another object of our invention is to provide an improved connection between the side and end sheets of the superstructure and between the same and the underframe.

Another object of our invention is to lower the center of gravity of the vehicle, particularlv when it is loaded.

hese and various other detail objects are attained in the structure illustrated in the accompanying drawings in which Figure 1 is a longitudinal top view of our improved underframe casting.

Figure 2is a longitudinal vertical section taken on the center line of the casting.

Figure 3"'is .a side elevation of the casting.

Figures 4, 5, 6, and 7 are verticaltrans verse sections taken on lines 4- -4, 5-5, 6-6, and 7-7 of Figure 1.

Figure 8 is a vertical transverse section taken on line 8--8 of figure 1 andvshowing the superstructure applied to theunderframe,

Figure 9 is a detail side elevation of one corner of the tank and underframe structure.

Figure 10 is a transverse horizontal section taken on line 10-10 of Figure 9.

Figure 11 is a vertical-transverse section illustrating a modified form of our invention.

Figure 12 is a horizontal section corresponding to Figure 10 but illustrates a modification in the connection between the side and-end plates of the tank structure.

The underframe of our improved vehicle structure is preferably formed'of a one-piece casting comprising spaced center sills 110$ RAILWAY VEHICLE STRUCTURE.

substantial depth and suitably flanged for relnforcem'ent, transom members 2, 3, and 4, end-sills 5 and 6, and side sills 7. At the transoms- 2'and 4, which form the bolsters, center sills 1 merge with the draft sills 8 wfilch extend between the bolsters and end s1 s.

A horizontally disposed web '9'extends between the side sills and draft sills and transoms and end sills and also between the center sills and is substantially imperforate throughout its area, being provided, however, with suitable openings 10 for connection to pipe'svleadin tothe engine.

depressions 30 which are arched longitudinally of the Hnderframe and serve to accommodate the truck wheels. The vertical side wall 31 of these recesses'are braced by ribs 11 and the flat area of web 9 is also braced by suitable ribs 12.

Between the front draft sills 8, the underframe is open upwardly and downwardly, the inner endof this space being closed by the adjacent bolster and the outer end of this space being closed by the corresponding endsill. Transverse members 13 are formed integral with the front end of the forward Web 9 1s also provided wlth upwardly extending draft sills 8 and form pockets for draw bar equipment.-

Each side sill is provided with a raised pad 14, which may be machined, and is adapted .to have ,the superstructure side plate 15 applied thereto and secured either by welding (as indicated at W), or riveted directly to the underframe or to a connecting'angle iro'n.

The rear end. sill 5 has a pad 16 on its upper face (sec Figures'l, 9, and 10) the end porton of the pad being rounded andcut 'away so that its outer edge does not project beyond the outer face. of the'pad 14 on the side sill,

The'tank end plate 17 rests upon and is welded to pad 16 of. the end sill. The end plate 17 is curved as shown and overlapped and .welded' or otherwise secured to side plate 15.

Spaced from the side plates 15 in the front portion of the tender are suitable partition plates 19 and an inclined floor plate 20and it willbe understood that these plates form a coal compartment in the forward center We clalmz.

lo the tank by the one-piece underframe de-- scribed eliminates the material and labor required for assembling tank bottom plates with an underframe and also providesa low center of gravity for the vehicle body struc- '15 ture especially when loaded, as a substantial part the water or other liquid is carried elow the top of the underframe.

It will be noted that suitable openings 32 are provided in the transoms and center sills to 'ermit free passage of liquid from one en of the tank to the other. in the modification illustrated in Figures 11 and 12, the underframe includes a centersill 21, a flanged side sill 22 and anintegral horizontal web 23. The superstructure side plate24 is connected to the-underframe by means of an inturnedflange 25 which .ma

' Y Y be riveted, as shown or welded tothe under; frame. A similar' ,ange connection 26'may 30 be used for the end plate 27. Like the-preferred structure, this modification contemplates the use'of a one-piece casting forming the bottom and the lower portion of the sides and ends of the t k. r 85 ormed by to ether.

gbviously other modificationsin the details welding the edges of the plates 40 of-our invention may be made-by those skill 'ed in theart without departing from the spirit of our invention. We contemplate the {exclusive use of such modific'ationsas fall' 5 1 within the scope of our claims.
